What part do I need to correct this problem. The nailer drives one nail but won't advance nails
Jim For model number SENCO SCN40R COIL ROOFING NAILER - March 30, 2023

Hi Jim, Thank you for your question. If your nail gun will not feed the nails after the first one, there are some parts that you will need to check to see which one is causing the issue. We recommend checking the the spring, the pin, the pusher, the magazine, the hub, and the nails. We have included a link from our website that you may reference on how to check these parts, https://www.ereplacementparts.com/repair-center/power-tool/nailer/nails-won't-feed/. Once you have determined the part you need, please call customer service. We look forward to hearing from you!
